Replace Vinyl Windows

If you replace the entire window--glass and frame--this is a good time to check caulking and insulation to stop any future leaks.

If you replace the window in the existing frame, you keep the existing vinyl windows frame and replace the sash and window panels. If the windows in your home are slightly out of square, this is a good option.

How to Repair Vinyl Windows

To replace vinyl windows, have the following on hand:

Sash replacement kit from manufacturer (if using)

Replacement glass

Jamb liner (insulation, weather stripping)

Caulk

Utility or razor knife

Screwdriver

To replace the glass, remove the glass carefully from the frame. Slide the new window into the sash, seal with silicone caulk, and slide the unit back into the vinyl frame. The caulk should set within 24 hours. Remove any caulk from the window with rubbing alcohol dabbed on a rag.

If the vinyl window lock is broken, you may be able to just replace the lock mechanism.
